independent travel from Shanghai to Suzhou

Hi guys, i would like to ask if I wanna travel to Suzhou by myself, is it easy to travel around? what i'm planning to do is to go to Suzhou from Shanghai then go to one of the water town near by, i would like to ask which water is better and easier to visit? and how long it will take normally to finish sightseeing the water town? Thanks a lot for help! :)
